Simplify expression 1/4 •3(8a-5b-4)-(4a+1)+4b

pychu [463]

Answer:

(8a+b-16)/4

Step-by-step explanation:

1/4×3(8a-5b-4)-(4a+1)+4b

Simplify:

-4a-1+4b+1/4×3×8a-1/4×3×5b-1/4×3×4

=1/4xax24-4a-1/4bx15+4b-1/4×12-1

=1ax24/4 -4a - 1bx15/4 +4b -1×12/4 -1

=ax24/4 -4a -bx15/4 + 4b -12/4 -1

= -4a + 24a/4 + 4b - 15b/4 -1 -3

= -4a + 6a + 4b - 15b/4 - 4

= 2a + 4b - 15b/4 - 4

= 8a + 16b - 15b - 16 / 4

= (8a + b - 16) / 4

= 8a + b - 16 / 4

Elis [28]

Answer:

Area of square yard is 289 square units.

Step-by-step explanation:

Problem: find the area of yard

Given

side measure of yard is equal to length of garage.

Dimension of rectangular garage : 17 by 10

we know that rectangle consist of 4 sides with opposite of equal length.

Additionally in rectangle value of length is always greater than measure than width of rectangle.

Thus, in the given dimension 17 by 10, 17 is greater than 10.

hence length of garage is 17

this length is equal to side of square yard.

Thus, measure of yard = 17

we know area of square is given by = $side^2$

thus, area of square yard = $17^2$ = 289

Area of square yard is 289 square units.
